Renewable Energy Control Systems using PV Solar and Wind Turbine

Our Renewable Energy Control (REC) system is designed to allow the easy implementation of an efficient and integrated renewable energy system. The system comprises the following:

  • Renewable Energy Control
  • Battery pack
  • Battery isolator
  • PV solar array
  • PV solar connection box
  • Wind turbine if a hybrid system is ordered
  • In many applications in many countries PV solar will provide all the energy required. In countries further north or south of the equator the energy from the PV solar in the winter months is lower and it is more difficult to get enough power. Usually in these countries during the winter months the power available from the wind is higher so a wind turbine will normally compensate and make the system more practical. The system is designed to make it easy to connect PV solar or wind turbines or both PV solar and wind turbines. The system can be implemented to get the best out of renewable energy in virtually every country in the world.


    The Renewable Energy Control is a package including an inverter, charge control and display. All the facilities are fitted as standard to make it straightforward to install and to enhance the performance. It is an automatic, integrated and robust system designed and manufactured to give many years of reliable and efficient service. Hypwr can supply the complete system with the REC (Renewable Energy Control), PV solar panels or wind turbine or both, connection boxes, isolators and battery. If a complete system is not required Hypwr will supply the Renewable Energy Control system along with other equipment as needed. The Hypwr Renewable Energy Control system is the complete answer to off-grid systems relying on renewable energy.


    The diagram on the right shows the main blocks of the Hypwr REC system. When the sun is shining on the PV Solar Array electrical energy is produced passing current through the PV Solar Connection Box to the REC Charge Control. The Charge Control ensures that the Battery is fully charged periodically and is not discharged too deeply. The battery stores the energy that is not being used so that power is available when the sun is not shining. Systems can be supplied that will work with a mains connection or a standby generator.


    The inverter uses energy from the battery to produce 230VAC 50Hz sinewave power to be used in the property. The output is a mimic of mains electricity and will run any mains appliance within its rating. The inverter fitted into the Hypwr REC system is robust and reliable with a long service life. It is straightforward to service and repair. The block diagram below shows the main component parts. The Inverter is microprocessor controlled. The control monitors the parameters during operation. It generates the waveforms to drive Transformers 1 & 2 via the Power Modules. The Power Modules can switch heavy DC currents efficiently and reliably and are rated at less than 50%. The output of the power stage can be shorted as shown on the block diagram and the power modules will shut down without damage. This is a rare achievement and demonstrates the robust design. The inverter can be operated at 50% overload for 15 minutes and 25% overload for 30 minutes. The output can be short circuited for 30 seconds and when the short is removed the load will power up as normal. To increase efficiency one transformer is switched off when it is not needed and switched on again when the load increases. The output is immune to virtually everything that will be encountered driving mixed and variable loads making the inverter ideal for this application.

    The front panel is designed to give information, warnings and alarms. The panel gives information to make the system more efficient.

  • “Press and Hold/Inverter On/Off” red button -> The inverter is switched on and off by pressing and holding the red button.
  • “Systems OK” green LED -> The LED is on when the system is OK with no faults.
  • “Output On” green LED -> The LED is on when the inverter is on and the output is live.
  • “Power Supply Fail” red -> LED The LED is on if one of the two DC to DC converters fails. Each converter can power the machine independently.
  • “Charge Fail Reduce Consumption” red LED -> This LED is on if the battery has not had enough charge over a twenty four hour period. The solution is to use less electricity to allow the battery to reach the right level of charge. The high charge takes place once per week.
  • “Audible Alarm Reset” blue button -> This button is used to silence the audible alarm.
  • “Battery Charge Discharge” meter -> The battery voltage and charge/discharge current is displayed. The voltage and current are toggled by pressing the adjacent blue button. The amber LEDs indicates the current status.
  • “Battery Charge Discharge” LED bargraph -> The battery is charged using a sophisticated and unique method. Little buckets of energy are counted into and out of the battery so the available capacity is known and can be indicated.
  • Charge Control

    On most renewable energy systems the batteries do not perform very well and often fail prematurely. This is usually because the system does not control the charge/discharge properly or give the user enough information. The power produced by renewable energy is variable over the 24 hour period. A wind turbine will produce power when it is windy; PV solar panels will only produce power during daylight. PV solar usually peaks at midday. The load is also variable throughout the 24 hour period. Hypwr have developed a charge control system that measures the power into and out of the battery in Amp/seconds. Similar to little buckets of energy being put into and taken out of the battery all the time. The little buckets of energy are counted so the control knows how many buckets of energy there are in the battery at any given time. The information is displayed on the bargraph and used to manage the system to give reliable operation and maximize battery life. The system gives a warning if the net energy into the battery is too low over a period of time. This can be rectified by reducing the consumption of electrical power allowing more energy to go into the batteries.


    Premature battery failure is common on renewable energy systems. So much so that manufacturers are reducing the warranty when the batteries are to be used on renewable energy systems. Suppliers cite high temperature, excessive cycling and other factors as the cause of the problem. Sometimes these conditions will affect battery life but the main cause of premature failure is because the Power Systems. Practical automatic solutions for saving fuel and reducing pollution.

Hyper specialize in integrating renewable energy into the systems where possible. Increasing efficiency and reducing fuel consumption.

    A hybrid renewable energy system utilizes two or more energy production methods, usually solar and wind power. The major advantage of solar / wind hybrid system is that when solar and wind power productions are used together, the reliability of the system is enhanced. Additionally, the size of battery storage can be reduced slightly as there is less reliance on one method of power production. Often, when there is no sun, there is plenty of wind. In comparison to solar modules, wind turbines can offer a more favorable price per watt ratio. Solar Online Australia's hybrid systems utilize the industry's leading high quality components to ensure reliable performance and long life. Our packaged systems are ideally suited to remote homes, schools and other off-grid applications. They can also be retrofitted to existing diesel-generator systems to save on high fuel costs and minimize noise. We have standard hybrid systems available to meet your power needs. We can also tailor a system to suit should you have a smaller or larger power requirement.

  • Our standard hybrid systems incorporate a 1kW turbine to produce the bulk of the power. The systems includes 3 to 4 days battery backup to cater for periods with little wind or sun. With the two methods of power production the battery backup will generally last longer than the designed backup period as there will almost certainly be some power input from one of the sources. The power production figure is based on an average of 5.6 Peak Sun Hours per day and an average wind speed of 5.4m/s. Many locations throughout India have averages exceeding these figures. The performance of the system will be relative to the figures for your site.
